Application led October 18, 1911.

T0 all whom 'it may concern:

Be it known that I, CHARLES F. McBnn, a citizen of the United States, residing in Athens, county of Athens and State of Chio, have invented a new and useful Improvement in Bookbindings, of which the following is a specification.

My invention relates to an improvement in loose leaf binders wherein a temporary binder leaf is initially employed in conjunction with a permanent binder device, the temporary binder leaf being provided with means for locking or clamping to the permanent binder devices and being expansible relative thereto; the temporary binder leaf also being provided with means for receiving a portion of a collocation of loose sheets for temporary separation of said sheets at a desired point; and the permanent binder being adapted for use independently of the temporary binder leaf When a collocation of loose sheets therein is complete and ready for permanent binding.

The object of this invention is to provide an improved construction for loose leaf binders.

A further object of this invention is to provide improved temporary locking means for a loose leaf binder.

A further object of this invention is to provide improved permanent locking means for a loose leaf binder.

A further object of this invention is to provide improved means for separating and separately maintaining the parts of a collocation of loose sheets in a binder during the operation of abstracting a single sheet or a plurality of successive sheets for temporary use or treatment extraneous to the binder.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which- Figure I is a plan of the complete device in extended position. Fig. II is a transverse vertical section on the line II--II of Fig. I, dotted lines indicating closed position of a permanent binder leaf. Fig. III is a detail vertical section on the line III-III of Fig. I, on an enlarged scale, dotted lines indicating a clamping device in inoperative position. Fig. IV is a detail vertical section on the line IV-IV of Fig. I, on an enlarged scale. Fig. V is an end elevation showing the temporary binder leaf in an auxiliary Specification of Letters Patent.

position assumed at times. Fig. VI is an end elevation showing the permanent binder containing a collocation of loose sheets, dotted lines indicating closed position of the binder.

In the construction of the device as shown the numerals 10, 11 designate permanent binder leaves, which leaves are flexibly connected at their rear margins to a back 12. 'Ifhe cover thus formed may be of any desired size and may be constructed in any suitable manner, as of board covered with cloth or canvas and suitably finished. Stubs 13, 14 are iexibly connected to the inner margins of the leaves 10, 11 respectively, and said stubs preferably are of slightly less length and materially less width than said leaves. Tubular posts 15, 16 are fixed in any desired manner to and rise from the right hand stub 14 adjacent the ends thereof, and said posts are of approximately the same length as the width of the back portion 12. Eyelets 17, 18 are formed in the left hand stub 13 and are adapted to register with the posts 15, 16 at times. A temporary binder leaf 19 is provided and is formed with a stub 19a flexibly attached thereto at its left hand margin, the combined widths of the binder leaf and its stub preferably coinciding with the width of either leaf 10, 11. The stub of the temporary binder leaf 19 is formed with holes 19b adjacent its ends adapted to fit loosely on the posts 15, 16. Latching or clamping devices are mounted on the stub 19a and are adapted to engage the posts 15, 16 at times and lock the temporary binder leaf to said posts. Each clamp or latch (particularly see Fig. III) has a base plate or bar 2O secured to the stub 19a by rivets 21. The base plate 20 is formed with a hole 20a registering with the hole 19b in the stub 19a and adapted to receive loosely a post 15 or 16. A spring 22 is fixed at one end on one or more of the rivets 21, extends longitudinally above the base plate 20, and is formed with a longitudinal slot 23 adjacent its free end adapted to receive a post 15 or 16. A cam latch 24 is pivotally connected to one end portion of the base plate 2O by means of a pin 25 mounted transversely of an endopening notch 26 in said plate. The cam latch preferably is formed with a plane back margain adapted to lie flat on the upper surface of the stub 19a; and is formed with an irregularly curved front margin adapted to engage, raise and sustain the free end of the spring 22, which is curved upward slightlyv for sliding contact With said-cam. The location of the spring 22 and the slot 23 therein is such that when the spring is in elevated position (dotted lines Fig. III) said slot Will looselyengageand slide on a post-15 or 16 so that the temporary binderleaf may be Vleaf in any position in `which it may beV placed altitudinally of the posts.

Stiids 27, 28 are 'svvivele'd in and rise from the upper surface of the temporary'binder leaf-19 adjacent its right 'hand Amargin and spaced apart to 'correspond to `thespacing of the posts 15, 16. The stiids` 27,'28 are forked at 'their upper ends Sand embrace end por- 'tions of arched 'rods-29, 30, 'yvhiehrodsfare piv'oted'to "said studs by'pins 31. The arched rods 28, 30 may lbe folded flat 'against the upper surface of the temporary binder leaf 19 and lsecured in such position by means, lof springslips 32, v33v fixed tothe/upper surface of said leaf. The arched rods v29, 30' are formed With spindles (29?, 3:0'a offre'di'iced diameter on their free ends adapted ytobe received Within the open upperfends 'of thev v In practical use loose'sheets such Vas '34 are Vproperly apertured and are placed on the posts 15, 16 and then the temporary binder .leafV :19' is mounted on'said postsabove the 'sheets 'as sli'ovvnrin Fig. Hand lis secured by releasing 'the ca m latches2ll, The margins `off the 'sheets 34, are thus' firmly .hield between the stubs 14 and 'l'ea'and.areseon'relybodnd- YThey 'quantity of sheets 34 .may 'b'eaddedV to from `time to" time as desired-,f limited' only by thee'ilf'ecxtive length 0f the 'posts 1511i6. A o, Attim'es it s desirable toremove 'a single sheet 'or a. quantity 'of si'i'cces'si'vesheets from the binder, and it i'salso desirable to .provide means Vfor` Amaint'ainir'rg fthe f succession and vertical 'alinement 'of other shedtsvvhich may be mounted `above the sheets'to be removed. It is for this purpose I have provided the 'arched rods '29, 30. When it is desired to remove'fone orf more sheets from 'the interior of the pile 3'st`hetemporary binder leaf 19 is removed by the springs22' and said binder -leaf is mvedfto the .leftv to .the positi'onshovvnj in Fig., Y. The arched rods 29, 30 are'rai'sed to vertical vpositions and the syviveled studs 27,128 'are turned to cause said arched rods to assume positions in planes parallel w'vitli the transversemedium line of the leaf'.l In su'ehpositions the ends of the arched rods 29, 30

. project beyondth'e right margin of the leaf 19 and the spindles thereof arjeji'n vertical positions. The spindles 29a, 30a are'then inserted in the posts 115', 16. A portion v"of 'fthe sheets 34 maythen be raised on the posts 15, 16 andgtnrned'back-onthe arched rods 29, 30 to an inverted position on the binderleaf -Qytothe end of exposing the sheet to be removed. The spindles 2 9, 3()a are removed from 'the posts, the sheet noW on thetop of the pile may be removed and employed as c'lesir'e'd, 'the Aremaining sheets being maintained in separatepiles by the posts 1 5, 16

andthe arched rods-29,330. V'The arched rods V29, 430 are again placed in position as coitinf nations of'the posts 15;, 1 '6 when it is desired to return. the separated/sheets to the original Y pile.

When acolloca'tion'of sheetsBLl isocompl'ete and it isy desired to Abind' ltheinv permanently lthe temporary binder leaf 19 vis removed from the Yposts 15 16 the leaf V10 -is raised tobring fthe stiib 1'3 overtheipp'er ends of'saidZ posts, as suggested in Fig; II.
